Fixing of the pipelines for water connections is only possible with the help of a battery gauge. For prefabricated installations it is necessary to make use of a special frame, by which the piping connections can be accurately established. This frame must later be removed.

The present invention relates to a pipe-spacing device for use in making wall batteries of cold-water and hot-water piping connections, with which device it is possible to fix the latter without a battery gauge and without the aid of a holder frame, and thus effect a great saving in working time.

According to the invention, this is achieved by a pipe spacing device comprising connecting sleeves which are provided on at least one side with coupling pieces and have allocated thereto spacing holders of different lengths and fitted at the front ends with countercoupling pieces into which the coupling pieces of the connecting sleeves engage.

In the drawing parts of similar functions are designated with the same reference numerals preceded by different hundreds integers.

Referring to FIGS. 1 6, the pipe-spacing device shown includes connecting sleeves 1,2,3 which are kept apart from each other by spacers 4,4',4" of different lengths according to FIG. 7 through 12. Said sleeves consist each of a pipe; insert l,2,3' which is embedded in a jacket 1",2",3 made of synthetic material. The sleeves l and 2 are provided at one side with a T-profile 5,105,205, while on sleeve 3 there is arranged a T-profile 5,105,205 at each of the two sides and also below. The T-profiles 5,105,205 serve as coupling pieces for fixing to the spacers 4,4',4" which in turn are each provided at their front ends with a substantially U-shaped profile 6,106,206 with inwardly bent-down profile arms 6'. The spacers 4,4',4" with their U-profile grooves can be pushed into the T-profiles 5 of the connecting sleeves 1,2,3 as illustrated in FIGS. 13 and 14. The spacers 4,4',4" have to be provided in various lengths of, say, 28,72 and mm. As shown in FIG. 13, three vertical pipes L and .a horizontal pipe I. are kept apart with respect to each other by means of connecting sleeves 1,2,3 and, as shown in FIG. 14, are mounted on a wall W by means of fixing screws 8 which pass through the spacers in fixing holes 7,107. The sleeves 1,2,3 may be laid to all sides and spaces in all directions.

In the represented further design of the pipe spacing device according to FIGS. 15 through 29, the sleeves 401,402,403 containing the pipe-inserts 401,402',403 have coupling pieces of substantially T-shaped profile 405,505,605 on their synthetic-substance jackets 401,403,402" surrounding the pipe-inserts 401,402,403. The spacers 204, 204', 204" are provided at both their ends with countercoupling pieces 206,206,204 for engaging with the coupling pieces 405,505,605. The countercoupling pieces 206,306,406 have a substantially U-shaped profile with inwardly bent-down profile shoulders 6'.

The connecting of the sleeves 1,2,3, etc., with the spacers 204,204',204, is effected by pushing the T-profiles 5 into the counterprofiles 206,206, etc.

For locking the position of the profiles in the middle of the whole sliding track, there is provided a notch connection 9,10;l09,1l0;209,210; of the coupling pieces 5,6,6';605, 206,206; etc. This notch connection is a groove and tongue construction, the tongue 9 being arranged in the middle on the outside of the T-profile piece 5,605,etc., and transverse to the direction of movement, while the groove 10,110,etc., is made at he bottom of the U-profile 6,6, etc., of the spacer 204,204,204. On the pushing the T-profile into the U- profile 206,206, etc., the tongue 9 falls into the notch groove 10, when the middle position of the pushing movement is reached.

For eliminating the playnecessary to facilitate erecting of the coupling parts 5,6,6, etc., that are pushed into each other, there are provided cams 11,111, etc., on the outside of the shoulder of the T-profile 5,105, etc., at a distance from the notch tongue 5,l05,etc. In the erected position of the coupling parts said cams rest resiliently on the bottom of the groove of the U-profile 6, thus ensuring connection free from play.

In order to facilitate erection, the sleeves 1,2,3, etc., may be provided at one of their connecting ends with a tapered mouthpiece 12,112,212, etc., which is thin-walled and therefore easy to cut away.
